Halo Clyde McCoy Wah Replica Circuit Board (Populated)

Halo · pedal

This is a circuit-accurate replica printed circuit board for the Clyde McCoy era Vox wah, populated with all components already soldered rather than sold as a bare board, aimed at the DIY pedal-building and wah-modding community. The Clyde McCoy designation refers to the specific inductor and potentiometer values found in the earliest, most prized run of Vox wah pedals, named after the trumpet player whose muted-horn playing inspired the wah effect's vocal quality, and remains the benchmark tone that later Vox and Dunlop Crybaby wahs are measured against. Halo produces these boards specifically so builders can source an accurate reproduction of that original circuit without hunting down vintage parts.

What stands out

  • “DIY pedal builders and wah enthusiasts use boards like this specifically to build or restore a wah pedal that matches the vocal, throaty sweep the original Clyde McCoy circuit is famous for,”

    — from the community notes

  • “For builders chasing the specific vocal character of the earliest Vox wah circuits, a pre-populated, circuit-accurate board like this , which vary …”

    — from the reviews

  • “The standout caveat is that a populated board alone , it still requires an enclosure and the remaining hardware to become a usable effect”

    — from the community notes

  • “In a chain a finished wah built from this board sits at the very front, ahead of gain and modulation effects, in the traditional wah position”
